Hello,

I have a 1960 TR3A. I just received my Dayton wire wheels. I want to put new tires on them. Should I use a radial tire? Any brand recommendations?

Thanks,

Bruce

Radial tires will work fine; these cars were even available new with (optional) radials.

Sorry I don't have a brand to recommend. It's getting tough to find tires in those old skinny profiles, so you'll probably have to settle for whatever you can find. I run TR6 wheels with relatively low profile tires, and even the Bridgestone Potenzas that I like have been discontinued in the size I use. I just picked up a pair of Kumho Ecstas, but haven't had a chance to try them yet.

What size (width) wheels did you get?? That will pretty much determine the max size tire you can use. When I got new wire wheels for my TR3, I bought a larger then stock size (5.5" vs 4.5"winking smiley and put on 185/70-15s, which are much more readily available then the 165R-15s needed for the 4.5" wheels.

Coker Tire and Universal Tire show several 156R15 tires, although it looks like both have the same selections.

I just ordered a set of coker firestones to go on my painted wires from moss. They're 165/80/15's I believe and cost about 80/each. Radials will give you a safer ride and cost less (yes, amazing, but true) than bias ply. Bias ply will grab, and then they wont.

These cars arent meant to run wide wheels and tires-too wide and you'll lose the handling and transmit to much force back up through the suspension. Unless of course youve gone totally custom andpout 5 bolt hubs and 4 wheel disks and opened up the wheel wells and beefed up the suspension (a lot).

Mebbe so, but 5.5" wheels and 205/55 tires isn't yet "too wide". I'd run wider except they won't fit between the frame & stock rear fenders. But I will agree that the handling is no longer limited by the tires, without also adding some sway bars. I've had the TR3 on the autocross track exactly once, and it says "1st place" on the trophy, so I don't really think I lost much in the way of handling smiling smiley

Sorry that wasnt my point, with wider wheels and tires, the handing will be heavier and more force transmitted up and through suspension resulting in more than average wear over time. Back in the day, you can see tr3's and similar vehicles essentially drifting and achieving great results even on bias ply tires.

What I meant is that you would lose the light and lively handling associated with using the smaller wheels and tires, not that you would *lose the handling outright*

I have learned that the tr3 is a very tightly interconnected system; and much more complicated than what might be readily apparent and when changing one thing, it usually impacts another more than anticipated.

Just my two cents.

Congratulations on the trophy!

I like the the 205's on 5" wheels, but went back to the 185's because of fender rubbing when turning. Also they wont fit in the rear tire hatch. I use a 4.5" with a 155 for a spare and yes, it's the most expensive tire for the car.

Definitely true. I use a 15" "Compact spare" I got for $10 at a junkyard, mounted on a stock TR3 rim. At least in theory, the compact spares are not supposed to age out like road tires do. A rolled up blanket takes up the extra space, and provides a cushion to kneel on if I do need to change a tire.

I just bought some wire wheels from Dayton. They were supoded to be the tubeless type but they leaked air. I mentioned it to their agent over here and they paid for the supply and fitting of tubes.
Great company Dayton but make sure you put tubes in the tyres.

Along the same lines, my new TR3B (still in the shop...sigh) came without a spare tire or wheel, so I need to come up with one. The wire wheels on the car are nice, but very wide: 72-spokes, and something like 15x5.5", so wide that it won't fit in the spare tire well. The tires are 165/80r15.

Question: If I get a narrower wheel for a spare, like a 15x4.5", will it fit on the same hub adaptor?

Yup, same adapter, as long as it's a Triumph wheel.

I am also interested in a compact spare, but I thought it wouldn't fit on a standard TR3 rim because the tire is more narrow? Are there different "compact tires?"

They come in a few different sizes. The one I used is a T135/70D15; which usually goes on a narrower wheel (probably 4" ) but seems to work fine on a stock 4.5" TR3 wheel. I've only needed it once, but I drove over 100 miles at around 70 mph with no trouble at all. (Of course I don't recommend exceeding the speed limit shown on the tire, that's just what I did.)

Originally, I was hoping that the wheel it was on would fit the TR3. Had the right bolt circle, but wouldn't clear the calipers; so I had to move the tire to a TR3 wheel.

A T135/90 might be a better choice, but I didn't happen to stumble over one of those at the junk yard smiling smiley

Some years ago I got rid of the bias ply and purchased Michelin 165 SR 15's. I had the wide whitewall vulcanized on the tire. My 3 handles fine and looks great with the wide whites.
